The world population is expanding more rapidly than ever before; however, the area of arable land either available to, or remaining useable for, cropping agriculture is decreasing at an alarming rate. Further, our ability to continue to improve total crop yield via the use of traditional methods is also hastily-approaching transition from the once impressive exponential phase to plateauing out in the stationary phase of the production curve for global crop yield.
Two closely-linked abiotic stresses, drought and salt stress, are of increasing concern for modern agriculture to continue to achieve annual improvements to total crop yield and therefore, meet our food security target. A tremendous volume of research effort has been spent in recent years by the plant biology research community to; (1) advance our current understand of the mechanisms employed by plants to mount an adaptive response to drought or salt stress, and; (2) translate research findings made in experimental model plant species into the major crop species, including rice, wheat, maize, barley and soybean, to provide tolerance to these two stresses.
Much of the knowledge gained, or the research translated into crops species to date, has focused on the regulation of the expression genes that encode the protein products key to the biochemical or physiological pathways responsible for providing tolerance to drought or salt stress. We also now know that the regulation of gene expression is far more complex than previously thought, with the ‘central dogma’ of molecular genetics, that is; from DNA template, to RNA intermediate, to protein product, being challenged on an increasingly frequent basis.
This Special Issue of Agronomy, titled “Gene Expression Regulation during Drought and Salt Stress in Crop Plants” will focus on the recent advances made by the plant biology research community on the complexity of the regulation of expression key genes involved in a crop plant’s response to drought or salt stress. We, therefore, warmly welcome novel research findings, review articles and opinion pieces covering the broad, yet related areas of; epigenetics (including chromatin modification and DNA methylation); genetic diversity (including natural variation); alterations to transcription factor expression; small RNA-directed RNA silencing (including the microRNA and small-interfering RNA species), and; the use of a transgene-based approach to molecularly manipulate gene expression in crop species to provide tolerance to either drought or salt stress (including the in planta application of the new sequence-specific nuclease toolkit for targeted mutagenesis).

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs).
